Embodiment 1

[0058] Such as Figure 1a As shown, the detonator system 10 provided by the embodiment of the present invention includes an electronic delay line 12 , a plurality of delay detonators 14 and a connector 30 for connecting the delay detonators 14 to the electronic delay line 12 .

[0059] refer to Figure 1b, the electronic time delay line 12 comprises several time delay relays 16, each time delay relay comprises a timer 16A and a control circuit 16B, these time delay relays 16 are connected together in series by electrical conductors or wires 18 and 20 of indeterminate length . The time-delay relays connected by wires 18 and 20 are separated from each other by a fixed distance 22, and the length of the distance 22 can be determined according to needs, for example, it can be 2m, 4m or any other selected length. The size of the distance 22 does not affect the understanding of the present invention, but it is very important in practical application and should be paid attention to....

Embodiment 2

[0072] The detonator system provided in this embodiment is basically the same as that in Embodiment 1, the difference lies in that the time delay relay used is different.

[0073] Figure 7 The delay relay used in this embodiment includes a voltage sensing circuit 16B, a delay timer 16A, and a switch driver 78 connected to one or more output switches 58 . The above-mentioned components are housed in the housing 68 . Also contained in the housing is a decoder 90 . If an input voltage signal Vin acts on the input terminals 60 and 62, the decoder 90 decodes and identifies the input voltage signal. If the input voltage signal is encoded correctly, the voltage sensor 16B is activated. At this time, the function of the delay relay is similar to that of the aforementioned delay relay. This way, the circuit only works when the correct code is detected.

[0074] The delay relay is further improved by providing an input terminal 92 on the timer 16B which allows connection of a prog...

Embodiment 3

[0077] FIG. 8 shows another detonator system 10A provided by this embodiment. Similar to FIG. 1 , the detonator system 10A includes: an electronic delay line 12 and a detonator 14 . The delay line has been manufactured in the factory. The time delay relay 16 connects the wires 18 and 20 in a predetermined manner.

[0078] The difference from the previous embodiments is that in this embodiment the detonator 14 is connected to the time delay relays rather than to a wire between adjacent time delay relays so that the detonator system 10A operates in a similar manner and has substantially the same characteristics .

Abstract

The invention discloses a detonator system. The system comprises an array and a plurality of detonators, wherein the array is formed by connecting a plurality of time delay relays which are in series connection with each other; and the plurality of detonators are connected to the array according to a predetermined interval respectively. The invention also discloses another detonator system. The system comprises a plurality of detonators and a plurality of connecting parts which comprise time delay relays, wherein the detonators are connected with the connecting parts by adopting lead wires; and a first connecting part connected with a first detonator is connected to a lead wire between an adjacent second detonator and a corresponding second connecting part. The invention also provides corresponding time delay relays. By using the system, a precise time delay length between any two detonators can be determined, and the continuity and the effectiveness of the conversion of energy and signal from one end of a time delay line to the other end are ensured.

Description

technical field [0001] The present invention relates to the technical field of blasting, in particular to a detonator system and a control relay used for the detonator system. Background technique [0002] Different types of detonator systems exist, for example, shock tubes are widely used. Essentially, an impingement tube transmits an activation signal at a predetermined velocity to a detonator connected to the impingement tube but at a distance. The velocity of propagation and the planned pyrotechnic delay in each detonator determine the time interval between the activation signal acting on one detonator and the next. [0003] While the shock tube system works effectively, it does have its drawbacks. It is difficult for this system to determine the exact length of time delay between two adjacent detonators. On the other hand, the integrity of the shock tube detonator system cannot be tested without activating the individual detonators. [0004] It is also known to use ...
